When the pest control agent of the present invention is used for controlling a pest in the agricultural field, the amount can widely vary depending on the application period, application area, application method and other factors, and is usually in the range from 1 to 10,000 g in terms of the compound of the present invention per 10,000 m². When the pest control agent of the present invention is formulated into an emulsifiable concentrate, a wettable powder, a flowable formulation and so on, the pest control agent is usually applied after diluting with water so that the concentration of the active ingredient becomes 0.01 to 10,000 ppm, and a granule or a dust is usually applied as it is.

These formulations or water dilutions of the formulations may be directly sprayed over pests or plants such as crop plants to be protected from pests, or may be used in the soil treatment for the control of pests which inhabit the soil of the cultivated land.

Application can also be conducted by a method of directly winding the resin formulation formed into sheet-shaped, or string- or cord-shaped formulation around plants, disposing the formulation in the neighborhood of plants, or spreading the formulation on the soil surface at the root.
